摘要:
Methods and apparatuses are provided for managing packet data network (PDN) connectivity for a device. PDN connectivity to a local gateway can be managed at an access point with which the device is communicating based at least in part on received PDN connectivity parameters. The PDN connectivity parameters can include access points, related closed subscriber groups, public land mobile networks, etc., from which a device can request a PDN connection. The PDN connectivity parameters can be specific for the device and/or for one or more access point names. In addition, a subscription server or other core network device can communicate the PDN connectivity parameters to the device and/or the device can receive PDN connectivity parameters as a result of a failed PDN connection attempt to an access point.

Systems and methods for correlating multiple registrations from a single device are disclosed. A private ID used in an prior registration may be used to obtain subsequent private IDs. The subsequent private IDs may be used in subsequent registrations. An instance ID from an prior registration may be used in conjunction with different registration IDs in subsequent registrations.

Devices and methods are provided for system selection from a plurality of wireless system access technologies, such as a first group (e.g., 3GPP2 technologies) and a second group (e.g., 3GPP technologies). In one embodiment, the method may involve storing identification information pertaining to the first group in a database, wherein the database may concern the priority of ones of the access technologies pertaining to the second group. The method may also involve selecting a preferred access technology from one of the first and second groups based at least in part on the identification information stored in the database.

This disclosure enables a radio access network to control media data rates and codec parameters selected during multimedia session establishment. As the load on a radio network changes, operators desire to have the ability to control what data rate new multimedia sessions (e.g., VoIP) are to utilize, thereby allowing the operator to conduct a trade-off between voice/video quality and capacity during heavy loading periods. The multimedia communication session may be initiated with a determined guaranteed bit rate, where the guaranteed bit rate is requested, negotiated as one of several acceptable guaranteed bit rates, or based upon maximum system capacity, to take advantage of maximum data rate for the equipment in use. The session may also be initiated with a determined Quality of Service based upon either a network or user equipment installed policy.

Systems and methodologies are described that facilitate fetching a native security context between network nodes in a core network after an inter-system handover of a mobile device. For instance, a mobility message that is integrity protected by a security context (e.g., the native security context, a mapped security context, . . . ) can be obtained at a network node from the mobile device. Further, the network node can send a request to a disparate network node within a core network. The request can include information that can be used by the disparate network node to establish that the mobile device is authenticated. Moreover, the native security context can be received from the disparate network node in response to the request. Accordingly, the native security context need not be recreated between the network node and the mobile device.

Systems and methodologies are described that facilitate supporting VPLMN-autonomous CSG roaming in a wireless communication environment. A UE can access a CSG list server associated with a VPLMN. A trust relation can be established between the UE and the CSG list server, for example. Moreover, the CSG list server can update a VPLMN allowed CSG list associated with the VPLMN stored by the UE. Hence, the UE can receive the VPLMN allowed CSG list from the CSG list server associated with the VPLMN. Further, the UE can store the VPLMN allowed CSG list as part of an allowed CSG list. The VPLMN allowed CSG list can include one or more entries associated with the VPLMN. Moreover, the allowed CSG list can be under control of at least one operator and the UE.

Information is maintained to assist in determining whether an access terminal is allowed to establish communication with an access point associated with a closed subscriber group (CSG). For example, CSG subscription information for visiting access terminals may be maintained at a local server. In this way, a network may use the locally stored CSG subscription information for a given access terminal to determine whether to allow that access terminal to access an access point in the network. In addition, multiple CSG lists may be maintained at an access terminal. For example, an access terminal may maintain a first list that is updateable by an operator and a second list that is updateable by a user. Here, the updating of one list may be based on a change in the other list.

Systems and methodologies are described that facilitate supporting multiple access modes for a base station in a wireless communication environment. The base station can leverage hybrid, closed, or open access mode. A whitelist of a mobile device that successfully registers on the base station can be selectively updated to include a CSG ID of the base station. For example, the CSG ID of the base station can be added to the whitelist when the base station operates in closed access mode, while adding the CSG ID can be skipped when the base station operates in hybrid access mode. According to another example, the CSG ID can be selectively added based upon a received accept cause value. Additionally or alternatively, a CSG ID and an access mode indicator can be transmitted from a base station to a network node for implementing access control and/or paging optimization at the network node.

An access terminal may switch to a different mode of wireless network selection as a result of manual selection of a wireless cell set (e.g., a closed subscriber group) associated with one or more wireless cells. For example, if the user of an access terminal selects a closed subscriber group in a wireless network that is different than the current wireless network, the access terminal may enter a manual mode of wireless network selection, select the wireless network corresponding to the closed subscriber group, and register on a closed subscriber group cell in the selected wireless network. In addition, an access terminal may automatically switch to a different mode of wireless network selection (e.g., the prior mode) upon losing coverage of a wireless cell set. An access terminal may also automatically select a cell of a wireless cell set if the access terminal returns to a cell of the cell set within a defined period of time after losing coverage of the cell set. Furthermore, an access terminal may return to a prior wireless network upon losing coverage of a wireless cell set.
